Topic: do you have modify the trade logic in this fork? (Read 3761 times)

seems not the same issue.your issue is matching price.my issue is not filled my bid orders but others lower than me.

and if you care about the short position's profit,you should resolve it ASAP.because with this flaw, I can fill all margin call orders at feedprice/1.1 even there is many bid orders which have a high price than me. then sell these cheap BTS to the high bid orders.

I don't know who should take responsibility, but I'm sure it's not me.or your spoke man should talk the truth to others, the DEX will not take any responsibility for your asset securityif there is a bug make your money disapear, you take responsibility by yourself.

I don't know what happend to you?! and you want who to give you an apologize?! the community? the developer? the user? the Committee? the system?If you hate the system flaw, destroy it in your way.If you hate the BITSHARES, leave or destroy it in your way.

At that time, the problem was only a side remark on issue #338. There several reasons why it wasn't included, like* lack of manpower (at the time, [member=43274]oxarbitrage[/member] was the only paid developer)* the problem was not considered to be a serious one* nobody came up and asked for a fix, or offered to help - as you can see from that thread, general interest from the community was almost non-existant* we have a lot of issues regarding the market engine, so fixing this should be part of a bigger overhaul IMO

I don't know if you don't know what can happen with this flaw, or you don't care about others lost totally.in fact the users could have lost millions USD in these days if somebody attack with this flaw.

when the price drop down, some short possition will be margin call after several minutes,the attacker can borrow 0.1 CNY with collect rate just a little bit higher than the first debt position.in fact he can create many short position like this.

the other hand, the attacker create some bid orders prepare to fill the comming magin call orders. the bid price is feedprice/1.1

when the margin call happen, the small debt position will execute first, and make all bid orders be ignore just like what happend to mine 4 days ago.then the real big margin call orders will filled the attacker's bid order at feed price / 1.1

finally the attacker can sell these cheaper BTS to the bid orders which have be ignore just now.so he can earn 10% without any risk.

Shorters should know that they risk a 10% penalty when being margin called. None of the defined operational parameters are broken through this behaviour.IMO this bug is a flaw, but not a serious problem. It certainly doesn't justify an emergency fix, or whatever you expect.

I agree with [member=4465]alt[/member] , this needs to be fixed. If we continue to have the sharp price drops in crypto we are bound to have some margin calls and the losses will be much greater than they should have been. This should work properly by using your Smart asset to reduce the collateral first, then fill all orders until sold or until it reaches the margin call price.

have you told the shorters they will lose 10% even there are plenty of bid orders in the market?have you told the buyer their bid order can't be filled even their order is in the first position?this is just another joke from the core team.

as the most active trader in DEX,nobody ever told me about these rule.so where is my compensation?I remember the committee member [member=31]fav[/member] have told me I will get it of course.where is it now?
